Northern Shrimp in the Estuary and Gulf of St. Lawrence
Bibliographic record
Abstract
Status The stock status indicator for the Estuary is above the proposed upper stock reference with a very high probability in 2025, placing this stock in the healthy zone of the Precautionary Approach (PA). In 2025, the Sept-Iles, Anticosti and Esquiman stocks are placed in the critical zone of the PA with respectively a very high, neutral and moderately high probability. Trends The biomass for Estuary stock has remained high for four years. After years of decline, the biomasses for Sept-Iles, Anticosti, and Esquiman stocks have shown an increase, following historic lows recorded in 2023. The relative exploitation rates of the Sept-Iles, Anticosti, and Esquiman stocks have declined over the past three years, reaching historically low levels. For the Estuary stock, this rate has been stable since 2018, at values lower than those of previous years. In general, juvenile abundance observed over the past five years has been low in all four stocks. Ecosystem and Climate Change Considerations Although deep water temperatures have stabilized over the past three years, part of the northern shrimp population remains exposed to historically warm and oxygen poor conditions. The impact of predation by redfish is expected to decrease in the coming years, but remains at historically high levels. Stock Advice Although the Sept-Iles, Anticosti, and Esquiman stocks remain in the critical zone, an improvement in their status was observed in 2025. This positive trend could be partly attributed to the decrease in redfish predation as well as the reduction in fishing pressure. According to the harvest control rules, the projected maximum harvests for 2026 fishing season are:1,261 t for Estuary, 917 t for Sept-Iles, 2,009 t for Anticosti and 1,498 t for Esquiman.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
